To all .to/0m t may concern.'

Be 4ituknown that I, HORACE P. FARRING- TON, citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in Combination-Tools, of which the following is a specifica- This invention relates toan improved instrument suitable for use by machinists, mechanics,engineers or the like.

The primary object of the invention contemplates the provision of acompact, simple and inexpensive device which combines the advantages ofa square, wire gage, thread calipers and wrench.

- Another object of my invention resides in the provision of a tool ofthe above character which is simple in construction and,

reliable in operation, yet fully capablel of serving the purpose forwhich it is designed. A further object of the invention is to severaltools or instruments comprising my invention are mounted, the toolsbeing disi posed in relation to the said square, in such a novel andpeculiar manner as to provide a neat, compact and useful device.

The above and additional objects are accomplished by such means as areillustrated in their preferred embodiment in the accompanying drawings,described in the followin'" specilication and then more particularlypointed out in the claim which is appended hcretoand forms a part ofthis application.

In describing my invention in detail reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which :---v

Figure 1 is an elevation ot' an instrument or device constructed inaccordance with my invention. llig. 2 is a transverse sectional viewltaken through the stock ot' the tool, the blades being shown in.elevation, and the plates being inclosed within the cut-out or recessprovided therefor. Fig. 13 is a fragmentary view illustrating theconnection between the wrench head and the square stock. rig. 4 is anelevation of a poi-tion of the tool, showing the construction of thebevel gage, and Fig. 5 is an elevation of a moditied forni of wire gage.

Proceeding n ow to the description of the cilit-ated.

drawings wherein is illustrated the pre# fer-red form of my inventionthe numeral 1 designates the stock of an ordinary trysquare, to one endof which is secured in the usual manner, a blade 2 provided withgraduation marks 3 designating inches and the fractions thereof. Anelongated aperture or opening 4 is formed within the blade for thepurpose of measuring wire of various, size, as one edge of the saidaperture is provided with graduation marks as shown at 5 whereby suchmeasurement is greatly fa- Pivotally mounted within t-he stock l,through the medium of a pin 6 are a plurality of plates or blades 7 theedgesv gage, bevel gage, Sheet metal gage, rule, Q of which are.provided with screw-thread gages 8, formed within the plates 7 near theends thereof. )ne edge of the plates 7 has formed'tlierein a pluralityof cut out porl tions 9, the saine varying in size throughout theseveral plates employed in connection with the invention, therebyforming a wire `or sheet metal gage, thel purpose of which provide anordinary square, upon which the is obvious. A cutout portion or recess10 is y formed within the stock 1, the said plates 7 being pivotedtherein and adapted to normallv fold within the said recess when not `inuse, the pivoted end of the plates being rounded as atll to facilitatethe opening and closing of the plates as desired. When folded within therecess, the blades 7 will -i in no way interfere with the application ofthe tool for the various other purposes for which it is designed, theblades being so arranged as to permit the withdrawal of one blade at atime for determining the pitch of the screw thread in question.

U pon the opposite end of the stock 1 from thc blade 2,1 provide awrenchhead 12, the same being adj ustably mounted in alinement with thestock by means of a longitudinally extending exteriorly screw threadedstem 13 fitting within the said stock and extending throughout a portionof the length thereof7 the said head 12 being loosely mounted upon thestem 13 so as to slide independently thereof. A head 14 is formed uponone end of the said stem and isI adapted to tit within a recess lsformedwithin the Wrench head 12, whereby a-turning of the said head '14 willpermit separation of the jaws of the wrench formed by the inner face 16of the head and the outer end 17 of the stock. A rule 17', either formedintegrally with or secured to the head 12, projects from one edgethereof and is fitted within a longitudithereby forming an eiicienttwist-drill or retaining the rule in y nally extending slot 18 formedWithin one face of the stock 1, the said rule 17 having a iiange 18formed upon each edge thereof and extending throughout its entirelength, the flange fitting within the said recess 18 for roper place andguiding the same during tie opening and closing of the wrench head 12.The provision of the rule 17 permits use of the device as calipers fordetermining the diameter of pipes, rods or similar articles, the saidarticles fitting between the faces 16 and-17 after proper adjustment hasbeen obtained by the manipulation of thehead 12;

A bevel gage 19 having a straight edge 2O is pivotally mounted upon thestock 1, near the intersection point of the said stock and the blade 2,such pivotal mounting being created through the medium of 'a thumbscrew21. By loosening the screw 21 the gage 19 may be swung so as to bringthe straight edge 20 at variousvangles indicated as at 22 upon thestock 1. Lateral adjustinent of the gage 19 is permitted by reason of aslot 23 formed within the said gage.

' Referring now to the modification shown in Fig. 5 the elongatedaperture 4 of the preferred form is dispensed with and the blade 3 0in'the modification is provided with a pluralit of apertures 31 varyingin size as 'desire each aperture designating the size of the wire ortwist-drill acted upon,

wire. ga 'of the above character.

It wi be seen from the above, taken in connection with theaccompanying-'drawings that. the several tools 'or instrumentscomprlsing my invention lare disposed or formed upon the tryrsquare in aneat, compact and highly eiiicient manner; and that the severaltry-square attachments, when folded, occupy but a' minimum amount ofspace.

It will be understood that the above description and accompanyingdrawings com- Having thus fully describedmy invent-ion,

what I claim as new and desire to secure by Letters Patent, is l A toolincluding a body portion having a longitudinal groove formed in one facethereof, a rule strip fitting said groove, said strip being adjustablelongitudinally relatively to the said body, a head portion integral withthe said strip, the latter serving as a means preventing movement of thehead laterally independently of the body, an eX- teriorly threaded shankoperating within a threaded bore therefor extending longitudinally ofthe body and in parallel spaced relation to said groove, said shankextending through anA opening therefor Within the said head, and a knobformed upon the shank, said knob operating within a recess of the headto adjust the head and rule relatively to the body, as and for thepurpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
